Measurement object
: Oxygen concentrations in inert gases containing no flammable gas, silica, corrosive gas, or
liquid (including water vapor).
Measurement system
: Zirconia system
Sampling method
: Pump, aspirator, or no suction device.
For the sampling gas pressure in each sampling method, refer to the sampling gas
conditions.
Pump and aspirator suction flow rate
: Approx. 1.0 L/min.
Aspirator suction conditions
: Air or N

Fixed : Set to 0-10 ppm, 0-100 ppm, 0-1000 ppm, 0-1%, 0-10%, or 0-100%.
Partial : Lower value or upper value of range can be set.
Note : Span (upper value-lower value) is 20% FS or more of above fixed range.
Example: 200-400 ppm when fixed range is 0-1000 ppm, 20-40 ppm when fixed range is
0-100 ppm.
